Why Activity Analysis?

Cyclists
Runners
Triathletes
All Endurance Athletes

You train hard - but do you know if it's working?

Most platforms only show pace and power. Activity Analysis reveals your actual physiology - VO2max, VLamax, metabolic efficiency - from every training session.

Performance Tracking Over Time

Manual Analysis Takes Hours

Analyzing training data manually is time-consuming and error-prone.

Automatic Analysis

Activity Analysis looks at every workout automatically - VO2max, VLamax, training zones, metabolic efficiency.

Prevent Overtraining

Weekly summaries based on Mader's method help you avoid overtraining and optimize recovery.

Frequently Asked Questions

Everything you need to know about Activity Analysis

Activity Analysis currently supports direct sync with Garmin and Wahoo, with more platforms coming soon. You can also upload FIT files manually from any device. Your workouts are analyzed within seconds of syncing.
Activity Analysis achieves 90% accuracy for VO2max and VLamax compared to laboratory testing. When combined with our Powertest protocol, accuracy increases to 95%. This makes it the most accurate non-invasive metabolic analysis available.
A heart rate monitor is recommended but not required. With heart rate data, Activity Analysis can calculate additional metrics like cardiac drift and aerobic efficiency. Power data alone is sufficient for VO2max, VLamax, and metabolic analysis.
VLamax (maximum lactate production rate) determines how quickly you burn carbohydrates. A high VLamax is great for sprinting but causes faster fatigue in endurance events. Knowing your VLamax helps you train specifically for your goals - whether that's increasing endurance or improving sprint power.
Body Reserve is based on Prof. Mader's protein synthesis model. It tracks the balance between training stress and recovery at the cellular level. When Body Reserve drops below 60%, you risk overtraining. This gives you earlier warning than traditional metrics like TSS or Training Load.
Yes! Activity Analysis calculates your exact carbohydrate and fat consumption for each workout. This helps you plan nutrition for training and races. You'll know exactly how many grams of carbs per hour you need based on YOUR metabolism, not generic recommendations.
Activity Analysis updates your VO2max and VLamax after every workout. This means your training zones are always current. If you're improving, your zones automatically adjust. If you're tired or losing fitness, Activity Analysis detects this too.
Yes! Activity Analysis is included in the Premium subscription (€24.90/month or €199/year). This also includes the Smart Training Plan, Powertest, Race Simulation, and Aerotest. The first 30 days are completely free.
